please God just call it port

At this point, I'd rather that they would have put yellow lightning flashing on one of its sides rather than the wording. Visual queues are much easier to interpret in 1.5 seconds vs text. I see the text, I go ok is starboard... that means right is bad... I need to move... <BANG>.

That's the point of this mechanic.
Same deal with Tsukuyomi Extreme.

It's basically the same mechanic as Dark/Light Blade in that fight. The difference being that you actually can run out of the telegraphed attack on Normal there.

As for showing us the marker to learn the attack: the standard visual cue during the last fights for that was lighting up the floor dark blue during the attack so you can learn from that. Showing an AOE marker you can't react to feels like a raised middle finger to me, even if it's meant that way.
